# AI Setup
This doc explains how to setup your AI providers, their APIs and credentials.
**"Endpoints"** refer to the AI provider, configuration or API to use, which determines what models and settings are available for the current chat request.
For example, OpenAI, Google, Plugins, Azure OpenAI, Anthropic, are all different "endpoints". Since OpenAI was the first supported endpoint, it's listed first by default.
Using the default environment values from [/.env.example](https://github.com/danny-avila/LibreChat/blob/main/.env.example) will enable several endpoints, with credentials to be provided on a per-user basis from the web app. Alternatively, you can provide credentials for all users of your instance.
This guide will walk you through setting up each Endpoint as needed.
For **custom endpoint** configuration, such as adding [Mistral AI](https://docs.mistral.ai/platform/client/) or [Openrouter](https://openrouter.ai/) refer to the **[librechat.yaml configuration guide](./custom_config.md)**.
**Reminder: If you use docker, you should [rebuild the docker image (here's how)](dotenv.md) each time you update your credentials**
*Note: Configuring pre-made Endpoint/model/conversation settings as singular options for your users is a planned feature. See the related discussion here: [System-wide custom model settings (lightweight GPTs) #1291](https://github.com/danny-avila/LibreChat/discussions/1291)*
## General
### [Free AI APIs](free_ai_apis.md)
### Setting a Default Endpoint
In the case where you have multiple endpoints setup, but want a specific one to be first in the order, you need to set the following environment variable.
```bash
# .env file
# No spaces between values
ENDPOINTS=azureOpenAI,openAI,assistants,google
```
Note that LibreChat will use your last selected endpoint when creating a new conversation. So if Azure OpenAI is first in the order, but you used or view an OpenAI conversation last, when you hit "New Chat," OpenAI will be selected with its default conversation settings.
To override this behavior, you need a preset and you need to set that specific preset as the default one to use on every new chat.
### Setting a Default Preset
See the **[Presets Guide](../../features/presets.md)** for more details
A preset refers to a specific Endpoint/Model/Conversation Settings that you can save.
The default preset will always be used when creating a new conversation.
Here's a video to demonstrate: **[Setting a Default Preset](https://github.com/danny-avila/LibreChat/assets/110412045/bbde830f-18d9-4884-88e5-1bd8f7ac585d)**
---
## OpenAI
To get your OpenAI API key, you need to:
- Go to **[https://platform.openai.com/account/api-keys](https://platform.openai.com/account/api-keys)**
- Create an account or log in with your existing one
- Add a payment method to your account (this is not free, sorry 😬)
- Copy your secret key (sk-...) and save it in ./.env as OPENAI_API_KEY
**Notes:**
- Selecting a vision model for messages with attachments is not necessary as it will be switched behind the scenes for you. If you didn't outright select a vision model, it will only be used for the vision request and you should still see the non-vision model you had selected after the request is successful
- OpenAI Vision models allow for messages without attachments
---
## Assistants
- The [Assistants API by OpenAI](https://platform.openai.com/docs/assistants/overview) has a dedicated endpoint.
- The Assistants API enables the creation of AI assistants, offering functionalities like code interpreter, knowledge retrieval of files, and function execution.
- [Read here for an in-depth documentation](https://platform.openai.com/docs/assistants/overview) of the feature, how it works, what it's capable of.
- As with the regular [OpenAI API](#openai), go to **[https://platform.openai.com/account/api-keys](https://platform.openai.com/account/api-keys)** to get a key.
- You will need to set the following environment variable to your key or you can set it to `user_provided` for users to provide their own.
```bash
ASSISTANTS_API_KEY=your-key
```
- You can determine which models you would like to have available with `ASSISTANTS_MODELS`; otherwise, the models list fetched from OpenAI will be used (only Assistants API compatible models will be shown).
```bash
# without spaces
ASSISTANTS_MODELS=gpt-3.5-turbo-0125,gpt-3.5-turbo-16k-0613,gpt-3.5-turbo-16k,gpt-3.5-turbo,gpt-4,gpt-4-0314,gpt-4-32k-0314,gpt-4-0613,gpt-3.5-turbo-0613,gpt-3.5-turbo-1106,gpt-4-0125-preview,gpt-4-turbo-preview,gpt-4-1106-preview
```
- If necessary, you can also set an alternate base URL instead of the official one with `ASSISTANTS_BASE_URL`, which is similar to the OpenAI counterpart `OPENAI_REVERSE_PROXY`
```bash
ASSISTANTS_BASE_URL=http://your-alt-baseURL:3080/
```
- There is additional, optional configuration, depending on your needs, such as disabling the assistant builder UI, that are available via the [`librechat.yaml` custom config file](./custom_config.md#assistants-endpoint-object-structure):
- Control the visibility and use of the builder interface for assistants. [More info](./custom_config.md#disablebuilder)
- Specify the polling interval in milliseconds for checking run updates or changes in assistant run states. [More info](./custom_config.md#pollintervalms)
- Set the timeout period in milliseconds for assistant runs. Helps manage system load by limiting total run operation time. [More info](./custom_config.md#timeoutMs)
- Specify which assistant Ids are supported or excluded [More info](./custom_config.md#supportedIds)
**Notes:**
- At the time of writing, only the following models support the [Retrieval](https://platform.openai.com/docs/assistants/tools/knowledge-retrieval) capability:
- gpt-3.5-turbo-0125
- gpt-4-0125-preview
- gpt-4-turbo-preview
- gpt-4-1106-preview
- gpt-3.5-turbo-1106
- Vision capability is not yet supported.
- If you have previously set the [`ENDPOINTS` value in your .env file](./dotenv.md#endpoints), you will need to add the value `assistants`
---
## Anthropic
- Create an account at **[https://console.anthropic.com/](https://console.anthropic.com/)**
- Go to **[https://console.anthropic.com/account/keys](https://console.anthropic.com/account/keys)** and get your api key
- add it to `ANTHROPIC_API_KEY=` in the `.env` file
---
## Google
For the Google Endpoint, you can either use the **Generative Language API** (for Gemini models), or the **Vertex AI API** (for PaLM2 & Codey models, Gemini support coming soon).
The Generative Language API uses an API key, which you can get from **Google AI Studio**.
For Vertex AI, you need a Service Account JSON key file, with appropriate access configured.
Instructions for both are given below.
### Generative Language API (Gemini)
**60 Gemini requests/minute are currently free until early next year when it enters general availability.**
⚠️ Google will be using that free input/output to help improve the model, with data de-identified from your Google Account and API key.
⚠️ During this period, your messages “may be accessible to trained reviewers.”
To use Gemini models, you'll need an API key. If you don't already have one, create a key in Google AI Studio.
Get an API key here: **[makersuite.google.com](https://makersuite.google.com/app/apikey)**
Once you have your key, provide the key in your .env file, which allows all users of your instance to use it.
```bash
GOOGLE_KEY=mY_SeCreT_w9347w8_kEY
```
Or, you can make users provide it from the frontend by setting the following:
```bash
GOOGLE_KEY=user_provided
```
Notes:
- PaLM2 and Codey models cannot be accessed through the Generative Language API, only through Vertex AI.
- Selecting `gemini-pro-vision` for messages with attachments is not necessary as it will be switched behind the scenes for you
- Since `gemini-pro-vision`does not accept non-attachment messages, messages without attachments are automatically switched to use `gemini-pro` (otherwise, Google responds with an error)
Setting `GOOGLE_KEY=user_provided` in your .env file will configure both the Vertex AI Service Account JSON key file and the Generative Language API key to be provided from the frontend like so:
### Vertex AI (PaLM 2 & Codey)
To setup Google LLMs (via Google Cloud Vertex AI), first, signup for Google Cloud: **[cloud.google.com](https://cloud.google.com/)**
You can usually get **$300 starting credit**, which makes this option free for 90 days.
### 1. Once signed up, Enable the Vertex AI API on Google Cloud:
- Go to **[Vertex AI page on Google Cloud console](https://console.cloud.google.com/vertex-ai)**
- Click on `Enable API` if prompted
### 2. Create a Service Account with Vertex AI role:
- **[Click here to create a Service Account](https://console.cloud.google.com/projectselector/iam-admin/serviceaccounts/create?walkthrough_id=iam--create-service-account#step_index=1)**
- **Select or create a project**
- ### Enter a service account ID (required), name and description are optional
- 
- ### Click on "Create and Continue" to give at least the "Vertex AI User" role
- 
- **Click on "Continue/Done"**
### 3. Create a JSON key to Save in your Project Directory:
- **Go back to [the Service Accounts page](https://console.cloud.google.com/projectselector/iam-admin/serviceaccounts)**
- **Select your service account**
- ### Click on "Keys"
- 
- ### Click on "Add Key" and then "Create new key"
- 
- **Choose JSON as the key type and click on "Create"**
- **Download the key file and rename it as 'auth.json'**
- **Save it within the project directory, in `/api/data/`**
- 
**Saving your JSON key file in the project directory which allows all users of your LibreChat instance to use it.**
Alternatively, you can make users provide it from the frontend by setting the following:
```bash
# Note: this configures both the Vertex AI Service Account JSON key file
# and the Generative Language API key to be provided from the frontend.
GOOGLE_KEY=user_provided
```
Note: Using Gemini models through Vertex AI is possible but not yet supported.

## Azure OpenAI
### Please see the dedicated [Azure OpenAI Setup Guide.](./azure_openai.md)
This was done to improve upon legacy configuration settings, to allow multiple deployments/model configurations setup with ease: **[#1390](https://github.com/danny-avila/LibreChat/issues/1390)**
---
## [OpenRouter](https://openrouter.ai/)
**[OpenRouter](https://openrouter.ai/)** is a legitimate proxy service to a multitude of LLMs, both closed and open source, including:
- OpenAI models (great if you are barred from their API for whatever reason)
- Anthropic Claude models (same as above)
- Meta's Llama models
- pygmalionai/mythalion-13b
- and many more open source models. Newer integrations are usually discounted, too!
> See their available models and pricing here: **[Supported Models](https://openrouter.ai/docs#models)**
OpenRouter is integrated to the LibreChat by overriding the OpenAI endpoint.
**Important**: As of v0.6.6, you can use OpenRouter as its own standalone endpoint:
### [Review the Custom Config Guide (click here)](./custom_config.md) to add an `OpenRouter` Endpoint
#### Setup (legacy):
**Note:** It is NOT recommended to setup OpenRouter this way with versions 0.6.6 or higher of LibreChat as it may be removed in future versions.
As noted earlier, [review the Custom Config Guide (click here)](./custom_config.md) to add an `OpenRouter` Endpoint instead.
- Signup to **[OpenRouter](https://openrouter.ai/)** and create a key. You should name it and set a limit as well.
- Set the environment variable `OPENROUTER_API_KEY` in your .env file to the key you just created.
- Set something in the `OPENAI_API_KEY`, it can be anyting, but **do not** leave it blank or set to `user_provided`
- Restart your LibreChat server and use the OpenAI or Plugins endpoints.
#### Notes (legacy):
- This will override the official OpenAI API or your reverse proxy settings for both Plugins and OpenAI.
- On initial setup, you may need to refresh your page twice to see all their supported models populate automatically.
- Plugins: Functions Agent works with OpenRouter when using OpenAI models.
- Plugins: Turn functions off to try plugins with non-OpenAI models (ChatGPT plugins will not work and others may not work as expected).
- Plugins: Make sure `PLUGINS_USE_AZURE` is not set in your .env file when wanting to use OpenRouter and you have Azure configured.

## Unofficial APIs
**Important:** Stability for Unofficial APIs are not guaranteed. Access methods to these APIs are hacky, prone to errors, and patching, and are marked lowest in priority in LibreChat's development.
### ChatGPTBrowser
**Backend Access to https://chat.openai.com/api**
This is not to be confused with [OpenAI's Official API](#openai)!
> Note that this is disabled by default and requires additional configuration to work.
> Also, using this may have your data exposed to 3rd parties if using a proxy, and OpenAI may flag your account.
> See: [ChatGPT Reverse Proxy](../../features/ninja.md)
To get your Access token for ChatGPT Browser Access, you need to:
- Go to **[https://chat.openai.com](https://chat.openai.com)**
- Create an account or log in with your existing one
- Visit **[https://chat.openai.com/api/auth/session](https://chat.openai.com/api/auth/session)**
- Copy the value of the "accessToken" field and save it in ./.env as CHATGPT_ACCESS_TOKEN
Warning: There may be a chance of your account being banned if you deploy the app to multiple users with this method. Use at your own risk.
---
### BingAI
I recommend using Microsoft Edge for this:
- Navigate to **[Bing Chat](https://www.bing.com/chat)**
- **Login** if you haven't already
- Initiate a conversation with Bing
- Open `Dev Tools`, usually with `F12` or `Ctrl + Shift + C`
- Navigate to the `Network` tab
- Look for `lsp.asx` (if it's not there look into the other entries for one with a **very long** cookie)
- Copy the whole cookie value. (Yes it's very long 😉)
- Use this **"full cookie string"** for your "BingAI Token"
-
### copilot-gpt4-service
For this setup, an additional docker container will need to be setup.
***It is necessary to obtain your token first.***
Follow these instructions provided at **[copilot-gpt4-service#obtaining-token](https://github.com/aaamoon/copilot-gpt4-service#obtaining-copilot-token)** and keep your token for use within the service. Additionally, more detailed instructions for setting copilot-gpt4-service are available at the [GitHub repo](https://github.com/aaamoon/copilot-gpt4-service).
It is *not* recommended to use the copilot token obtained directly, instead use the `SUPER_TOKEN` variable. (You can generate your own `SUPER_TOKEN` with the OpenSSL command `openssl rand -hex 16` and set the `ENABLE_SUPER_TOKEN` variable to `true`)
1. Once your Docker environment is ready and your tokens are generated, proceed with this Docker run command to start the service:
```
docker run -d \
--name copilot-gpt4-service \
-e HOST=0.0.0.0 \
-e COPILOT_TOKEN=ghp_xxxxxxx \
-e SUPER_TOKEN=your_super_token \
-e ENABLE_SUPER_TOKEN=true \
--restart always \
-p 8080:8080 \
aaamoon/copilot-gpt4-service:latest
```
2. For Docker Compose users, use the equivalent yaml configuration provided below:
```yaml
version: '3.8'
services:
copilot-gpt4-service:
image: aaamoon/copilot-gpt4-service:latest
environment:
- HOST=0.0.0.0
- COPILOT_TOKEN=ghp_xxxxxxx # Default GitHub Copilot Token, if this item is set, the Token carried with the request will be ignored. Default is empty.
- SUPER_TOKEN=your_super_token # Super Token is a user-defined standalone token that can access COPILOT_TOKEN above. This allows you to share the service without exposing your COPILOT_TOKEN. Multiple tokens are separated by commas. Default is empty.
- ENABLE_SUPER_TOKEN=true # Whether to enable SUPER_TOKEN, default is false. If false, but COPILOT_TOKEN is not empty, COPILOT_TOKEN will be used without any authentication for all requests.
ports:
- 8080:8080
restart: unless-stopped
container_name: copilot-gpt4-service
```
3. After setting up the Docker container for `copilot-gpt4-service`, you can add it to your `librechat.yaml` configuration. Here is an example configuration:
```yaml
version: 1.0.1
cache: true
endpoints:
custom:
- name: "OpenAI via Copilot"
apiKey: "your_super_token"
baseURL: "http://[copilotgpt4service_host_ip]:8080/v1"
models:
default: ["gpt-4", "gpt-3.5-turbo"] # *See Notes
titleConvo: true
titleModel: "gpt-3.5-turbo"
summarize: true
summaryModel: "gpt-3.5-turbo"
forcePrompt: false
modelDisplayLabel: "OpenAI"
dropParams: ["user"]
```
Replace `your_super_token` with the token you obtained following the instructions highlighted above and `[copilotgpt4service_host_ip]` with the IP of your Docker host. *****See Notes***
Restart Librechat after adding the needed configuration, and select `OpenAI via Copilot` to start using!
>Notes:
> - *Only allowed models are `gpt-4` and `gpt-3.5-turbo`.
> - **Advanced users can add this to their existing docker-compose file/existing docker network and avoid having to expose port 8080 (or any port) to the copilot-gpt4-service container.
